My battery was disconnected so I had to enter the password. Unfortunitly I had the wrong password so i kept entering the wrong thing when it said "code." Now the display says "err-3" and I cant get rid of it by entering my password or anything. Can anyone help me fix this because I cant use the cd player. thanks.

its a protection against people just trying random codes, so waht you need to do is leave the car with the key in the accessory position for about an hour then come back and then you should be able to put in your security code to get it working again

sadly, I have my code memorized i've had to use it so many times
